What Are the Main Parts of Your Heating Air Conditioning Unit?

It may be worth investing in a new unit in the event that your home’s air conditioner is a bit old and in need of repair. A residential HVAC professional can help you select the right option for your needs.

Gas-powered air conditioners, also referred to as propane air conditioners make use of natural gas to heat and running condensers.

Evaporator

The evaporator coil of your air conditioner is what cools your home. The evaporator is within a box attached to your gas furnace, or inside it (if you own one). If you don’t, the evaporator is located in an air handler. The evaporator is where the refrigerant liquid is transformed into a gas and absorbs heat from the home’s indoor air.

The evaporator is made up of one or more coils of copper which are tightly packed. The refrigerant is in low pressure when it reaches the coils, making it easier to transfer heat.

A fan blows warm indoor air over the coil that is used to evaporate the air. The air is then cooled through the removal of heat from the evaporator which changes the refrigerant’s temperature and lowers the temperature of your indoor air. The cool air is circulated through the ductwork of your home, and then to each room.

In contrast to the compressor, which needs to create refrigerant gas at high temperatures to allow efficient cooling, the evaporator only requires it to raise its boiling point to a lower temperature to allow for efficient air cooling. The evaporator also has its own fans to help it in achieving this objective.

The metering device of the evaporator assists to ensure that the refrigerant has the same amount of liquid inside it. The low-side floating is designed to be open when there is no liquid in the evaporator, and close when liquid enters the coils.

There are two types of evaporators: cased and uncased. A cased evaporator is the one you’ll most likely to see in your home because it’s contained within the metal casing of your air conditioning unit. A non-cased evaporator is the same however it doesn’t come with the outer shell that protects it.

Both evaporators have the same function, but it is important to choose a model that can meet the specific requirements of your home. For instance, certain models are more suited to more harsh working environments, whereas others are better suited to more moderate conditions. Consider how easy it is to clean and maintain your evaporator. This can save you money, time and hassle.

Condenser

Condensers are among the three major components of the cooling system in your home. They aid in the operation of the system efficiently. It is situated outside of the home, and is connected to the evaporator’s coil by refrigerant lines. It is also home to several metal fins and fans that work to remove heat from the refrigerant gas that has been transported here from the evaporator. The heat that is removed allows the refrigerant to cool down and transform back to a liquid state.

A compressor is attached to a condenser unit. It works to pressurize low-pressure liquid refrigeration that is pumped out of the evaporator coil. The squeezing action of the compressor raises the temperature of the coolant, which is then pumped into condenser coils to take in heat that is not being released from the air around it. Once the cooling cycle is complete the refrigerant will be pushed into the compressor, where it will be pumped under pressure before being sent back to the evaporator coil.

Since the condenser is situated outside, it is exposed to the elements. Leaves and twigs, grass clippings, or even roofing shingles, can damage the condenser. A universal HVAC condenser will protect your heating and cooling equipment from damage when it is not in use.

Do not shade the condenser. This can decrease the flow of air, causing the compressor to work harder in order to cool your home. This can result in higher energy bills and a possibility of losing refrigerant.

Regular maintenance of your HVAC system will ensure that the condenser is working effectively. Having a professional service technician look over every major component of your system on a regular basis can aid in preventing major problems from occurring. In addition having a professional service team check your refrigerant levels regularly will also help keep any problems from developing. By following these steps, you can help to extend the longevity of your cooling and heating system as well as reduce the cost of energy.

Compressor

A compressor is the center of your air conditioning unit, and it pumps refrigerant throughout the system to keep everything cool. It’s like the blood that flows through your body when it pumps the coolant between your evaporator coils and condenser. If the compressor fails then the evaporator won’t be able to perform its job and your house will become uncomfortably hot.

There are several different kinds of HVAC compressors and each has its own pros and cons. For instance the reciprocating compressor is comprised of pistons that move between up and down inside the cylinder. This action creates suction which draws in refrigerant. When the piston is moving downwards, it reduces gas volume. A discharge valve opens to let the pressurized refrigeration to the condenser.

This type of compressor is equipped with a clutch and a crankshaft which helps the piston compress the air. A rotary compressor is equipped with blades inside the cylinder, which help compress the air. This type of compressor is quiet, which makes it a popular option for residential use.

The HVAC compressors of both kinds are designed to raise temperatures of the liquid when it is compressed. This creates the formation of a high-temperature, high pressure liquid. Since heat naturally flows from high-temperature substances to lower temperature ones the hot vapor is able to move into the evaporator coils before it can transform back to its liquid state.

You can avoid the majority of AC problems by keeping up with your maintenance schedule. This will ensure that your AC will last for many years and provide peace of mind that your home will always be comfortable.

Thermostat

The thermostat is the brains of your cooling and heating system, allowing it to control the timing and manner in which it is turned on and off. It reads the air temperature and compares it with a preset desired level. If it is off by just a few degrees it will send an electronic signal to alter it to bring it closer to the desired temperature. The majority of modern thermostats employ a digital sensor called the thermistor, which measures the temperature. The thermistor consists of two different metals that expand at different rates when they heat up and bend in opposite directions. When the thermistor reaches its set temperature it sends a signal to the circuit board to switch on your heating or AC system.

The latest models of thermostats feature touchscreens that make them easy to use and program. Many thermostats can be programmed to automatically heat and cool your home at certain times. This saves you from having to set them manually each day. Additionally, they offer reports on energy usage so that you can figure out how to cut down on costs.

If you have an older electromechanical model, it’s slightly more complex. It is composed of a bimetallic band which is bonded to mercury the vial. When the temperature changes it causes the mercury inside the vial to shift in a way, interrupting or completing an electrical circuit. When the vial tipping, the thermostat turns on the heating and cooling system.

You should regularly clean your thermostat to remove dust. Also, ensure that it is not crooked or loose. In some instances the thermostat could be having trouble with its readings due to an unclean evaporator coil or the thermistor being damaged. In that situation, you’ll require an expert to fix the problem for you. If the issue is something else, like an unresponsive screen, you can try replacing the batteries or checking that your breaker hasn’t been activated. This is a good illustration of how your HVAC system will be more efficient if you spend the time to research it and make the most of its use.
